Use of magnetic carrier particles for selective phosphate recovery from waste water on a pilot plant scale.

For several years, particle technology research in Würzburg has been working on the development of magnetic carrier particles for use in water purification, selective separation and concentration of ions and analytics.
 

Challenge

Separation of dissolved substances from fluids, such as selective phosphate recovery from waste water, detection and/or removal of organic trace substances from fluids. The magnetic carrier particles can be adapted for a variety of tasks. These projects focus on the selective recovery of phosphates from wastewater, the removal of organic trace substances and the detection of very small amounts of water in solvents.
 

System

Micro-scale particles are equipped with magnetic nanoblocks which have switchable properties. Added to a fluid, the particles initially behave completely non-magnetic. By means of an external magnetic field, however, they can be transformed into strong magnets, thus enabling magnetic separation of the particles from fluids. If the surface of the switchable, magnetic carrier particles is now chemically tailored, it is possible to specifically bind substances dissolved in the target fluids to the particles and thus extract them from the fluid.
